Yes. While you can control only one Roku player at a time, you can switch quickly between Roku players on your network.
To switch to another Roku player in iOS, tap the settings icon on the Home tab and select the player to which you want to connect. If you have not previously connected to the player, tap “Find a Roku Device.”
To switch to another Roku player in Android, tap the switch Roku player icon in the upper right of any tab and select the player to which you want to connect. If you have not previously connected to the player, select “Find a New Player.”
